Lluvia De Estrellas
In short
The Orionid meteor shower reaches its peak today, 21 October 2026, with up to 20 meteors visible per hour. This celestial event is caused by debris from Halley's Comet entering Earth's atmosphere at high speeds.
In plain words
A meteor shower happens when tiny pieces of space dust hit our atmosphere and burn up. This creates bright streaks of light in the night sky. The Orionids are a specific group of these streaks seen in autumn.
A simple example
If you look up on a clear night during the peak, you might see a bright flash of light moving quickly across the sky.
Why it matters
It allows astronomers and hobbyists to study the composition of Halley's Comet. It also provides a rare, free natural spectacle for people to enjoy outdoors.
Easy to mix up
Do not confuse a meteor shower with a comet; a comet is the large object that leaves the dust trail behind.
